Voyager recently got added to F-Droid but can also be used as PWA from a web browser but personally I'm currently waiting until Infinity for Lemmy actually will get it's first stable release
Infinity is not too bad right now, I am replying from it right now. My only real issue with it is that I can't see whether people have responded to my posts/comments.
I can see replies to my comments and posts in infinity. The main issue is now that private messages aren't implemented. Depending on the speed of developement, it will soon land
I am presently using infinity from izzyondroid repository (is that the right name?) and it's good. However, some features are missing, such as blocking communities (at least I couldn't find the feature).
